The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.
Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe

The ability of metal materials to resist indentation of hard objects has a small circumference/area ratio on all geometric sections, i.e., large internal sections can be obtained with the same number of materials. Because of its low cost and high strength, steel pipe has been widely used in modern fluid transportation. According to the different production process, the steel pipe is divided into seamless steel pipe and welded steel pipe, they are divided into high frequency longitudinal welded pipe (ERW), spiral welded pipe (SSAW), submerged arc welded pipe (UOE) and so on. In the past, traditional seamless pipes were used for fluid pipelines.山东大鼎钢管厂

精密钢管是冷拔或热轧后的一种高精度钢管材料。精密钢管主要用于生产气动或液压元件,如气缸或气缸的产品,它们可以是无缝的或焊接的,但大多数是精密无缝钢。管。精密钢管具有尺寸精度高、表面光洁度高、热处理后管内外表面无氧化膜、管材无压扁裂纹、冷弯变形、耐高压、能进行各种复杂变形和机械加工等优点。深加工。主要生产钢管牌号:10, 20, 35、45、40Cr、42CRMO等。精密钢管;GB/T699—2008;GB/T3639-2008。
